Research questionHow can left ventricular ejection fraction be estimated from PLAX echocardiography when standard apical views are unavailable and labels are scarce?PLAX echocardiographic videos lack established labels for ejection fraction, while the clinical standard relies on apical views that may not be obtainable. This creates a need to estimate ventricular function from the available PLAX view.

Latest papersRecent research connected to this question, newest first.Learning from Scarce Labels: Multi-View Echocardiography for Ejection Fraction PredictionThe source presents over 25,000 proxy-labeled PLAX videos generated by correlating clinical notes with echocardiographic videos and reports a PLAX mean absolute error of 6.86%. It also reports 6.37% error after unweighted late fusion with A4C predictions and releases labels, trained models, and demos; these results do not by themselves establish clinical deployment.research paper · Sep 2, 2026
